Carbon fiber reinforced wood composite material and preparation method thereof

Abstract

The invention discloses a carbon fiber reinforced wood composite material and a preparation method thereof, belonging to the field of building structural plates production. The carbon fiber reinforcedwood composite material mainly consists of wood composite material and carbon fiber cloth. The reinforcement is achieved by partially sticking the carbon fiber cloth on the bottom of the wood composite material. The preparation method realizes the preparation of the wood composite material and the partial reinforcement of the carbon fiber cloth by a series of processes such as stock processing, end part gluing, end pressing, plane gluing, cold rolling, post-processing and the like. The method utilizes the carbon fiber to partially reinforce the wood composite material, thereby not only improving the mechanical strength and creep resistance of the wood composite material, but also reducing the variability of the wood composite material and meanwhile avoiding the problem of high cost causedby the massive use of the carbon fiber. The invention realizes simple preparation process and convenient operation and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a carbon fiber reinforced wood composite material and a preparation method thereof, and belongs to the field of building structural plate manufacturing. Background technique [0002] At present, due to the protection of the environment and forest resources in various countries, high-quality wood for the production of engineering wood composite materials is relatively scarce. Countries will focus on how to use artificial fast-growing wood and low-quality wood. Poplar and other artificial fast-growing tree species have a wide planting area and abundant timber reserves in my country, but they have not been well used due to poor materials and many defects. Carbon fiber is a commonly used reinforcing fiber with many excellent properties: high axial strength and modulus, no creep, good fatigue resistance, small thermal expansion coefficient, good corrosion resistance, low fiber density, but its cost is high .
